Such a perfect day (I’m glad I spent it with you)

I saw a great tweet from Marcus du Sautoy this morning who declared that today, June 28th, is a perfect day because both 6 and 28 are perfect numbers. This, combined with the fact that it is very sunny in Manchester right now put me in a great mood and I gave my colleauges a quick maths lesson to try and explain why I was so happy.

“It’s not a perfect year though is it?” declared one of my colleauges. Some people are never happy and she’s going to have to wait over 6000 years before her definition of a perfect day is fulfilled. The date of this truly perfect day? 28th June 8128.
